TECHNICAL OVERVIEW

Applications

Suitable for load-bearing installation of windows & doors within masonry, concrete & timber frame constructions.

Load Bearing Capacity

High compressive strength safely transfers structural loads into the building structure.

Airtightness

Supports continuous airtightness when used with suitable sealing membranes and tapes.

Thermal Performance

Reduces thermal bridging by positioning windows within the insulation zone.

Weather Performance

Compatible with weather-resistant sealing systems for durable external protection.

Certifications

Passive House certified component. Manufactured in Germany.

blaugelb Triotherm+ is a high-performance structural window installation system designed for the secure installation of windows and doors within the insulation zone of the building envelope. Manufactured from a dense, load-bearing EPS material, the system provides exceptional compressive strength while significantly reducing thermal bridging compared with conventional installation methods. By positioning the window in the optimum thermal plane, Triotherm+ helps improve the overall energy efficiency and long-term performance of the building fabric.

The system forms an integral part of a high-performance airtightness strategy when combined with the appropriate internal and external sealing products. Suitable for new-build and refurbishment projects, Triotherm+ provides a stable, durable substrate for airtight membranes and sealing tapes, ensuring reliable connections between the window frame and surrounding structure. The result is a robust installation that supports compliance with modern building regulations, Passivhaus principles and low-energy construction standards while enhancing durability, weather resistance and occupant comfort.

blaugelb Triotherm+ Benefits

Stable dimensions and volume
• Insensitive to moisture, non-ageing
• 100 % recyclable, 100 % free of HCFCs and HFCs
• HBCD (hexabromocyclododecane)-free
• High-density (expanded) polystyrene
• High ductility
• Thanks to 100 % reversibility of window fastening for renovation,
makes a major contribution to sustainable building
• Time savings thanks to few working steps and swift combination with
the system components
• Profiles are easy to machine/saw with a jigsaw or mitre saw (coarse
longitudinal-cut blade)
• Can be cut to shape precisely and with minimal dust
• Profiles infinitely extensible by dovetailing
– Very good fit of the dovetail joint
– High level of joint stability
– Waste-free processing
• Profiles exhibit a very low weight and compact dimensions
– Advantage for transporting to/on construction site
– Advantage for handling
• Window frames can be screwed on without pre-drilling of the
blaugelb Triotherm+ Profiles
• Waffe structure increases the adhesion of the seal between the base
and the blaugelb Triotherm+ Profiles
• Production process constantly maintains very high dimensional accuracy
and geometrical accuracy of the blaugelb Triotherm+ Profiles
– Always straight
– Always level sealing flanks
• High inherent stability and flexural strength, high ductility
• Airtight, connection between profile and base is verified by technical
tests
• Absorption of high building tolerances flush with windows is verified
by technical tests
• Reduces thermal bridges in the mounting plane of the assembly parts
• Tested to be very low in emissions according to EMICODE EC1 Plus
• Cradle to Cradle Certified® at the Silver level
